It's a very interesting topic this.
Here's a thought:
Rapid chargers at a long stay (all day+) parking destination.
E.g. Train station, park & ride.
Should someone need a charge who is going to be away from their car for quite a while/cannot return in 60mins etc, what should they do?
They'd either need to plug in when they get back to their car and have to wait around for however long, or more ideally they would want to plug in when they got there.
The solution seems to me to be, multiple parking spaces per charger, once their car has finished charging, it can be unplugged and used by another car in an adjacent space.
